LiClO 4 based polymer blend electrolytes (original) (raw)

Fixed ratio of poly (ethylene oxide)/poly (vinyl pyrrolidone) (PEO /PVP) and various concentrations of lithium perchlorate (LiClO 4) were prepared by solvent casting technique. The m aximum ionic conductivity value was found to be 0.2307◊10 -5 Scm -1 for 8 wt% of LiClO 4 based system at ambient temperature. Three dimensional topographic image of the sample having a maximum ionic conductivity show small micropores which are responsible for the high ionic conductivi ty. The change in viscosity of the prepared samples were line with the ionic conductivity.
